jQCloud is a jQuery plugin that builds neat and pure HTML + CSS word clouds and tag clouds that are actually shaped like a cloud

Installation

Installing jQCloud is extremely simple:

Make sure to import the jQuery library in your project.
Download the jQCloud files. Place jqcloud-0.2.10.js (or the minified version jqcloud-0.2.10.min.js) and jqcloud.css somewhere in your project and import both of them in your HTML code.

You can easily substitute jqcloud.css with a custom CSS stylesheet following the guidelines explained later.

Usage

Once you imported the .js and .css files, drawing a cloud is as simple as this:

<!DOCTYPE html>
<html>
  <head>
    <title>jQCloud Example</title>
    <link rel="stylesheet" type="text/css" href="jqcloud.css" />
    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script>
    <script type="text/javascript" src="jqcloud-0.2.10.js"></script>
    <script type="text/javascript">
      /*!
       * Create an array of objects to be passed to jQCloud, each representing a word in the cloud
       */
      var word_list = [
          {text: "Lorem", weight: 15},
          {text: "Ipsum", weight: 9, url: "http://jquery.com/", title: "I can haz URL"},
          {text: "Dolor", weight: 6},
          {text: "Sit", weight: 7},
          {text: "Amet", weight: 5}
          // ...other words
      ];
      $(document).ready(function() {
        // Call jQCloud on a jQuery object passing the word list as the first argument. Chainability of methods is maintained.
        $("#example").jQCloud(word_list);
      });
    </script>
  </head>
  <body>
    <!-- You must explicitly specify the dimensions of the container element -->
    <div id="example" style="width: 550px; height: 350px; position: relative;"></div>
  </body>
</html>

Word Attributes

For each word, you need to specify the following mandatory attributes:

text (string): the word(s) text
weight (number): a number (integer or float) defining the relative importance of the word (such as the number of occurrencies, etc.). The range of values is arbitrary, as they will be linearly mapped to a discrete scale from 1 to 10.

You can also specify the following optional attributes for each word:

url (string): if specifyed, the word will be wrapped in a HTML link (<a> tag) and the URL used as its href attribute.
title (string): an HTML title for the <span> that will contain the word(s)
callback (callable): a function to be called after this word is rendered. Within the function, this refers to the jQuery object for the <span> containing the word.
customClass (string): an additional HTML class for the word
dataAttributes (object): keys and values to be used as HTML5 data attributes for the word (e.g. {confirm: "Are you sure?", remote: true})
handlers (object): an object specifying event handlers that will bind to the word (e.g.: {click: function() { alert("it works!"); } })

Options:

Since version 0.2.0, jQCloud accepts an object containing configuration options as the second argument:

Tag: text effect
